Who we are.
Medina Diamonds is a B2B wholesaler of certified lab-grown and natural diamonds. We serve jewelers, designers and retailers with a carefully curated inventory of round, melee and fancy-shape stones — all backed by the industry's most trusted grading labs: IGI, HRD Antwerp and GIA.
To make wholesale sourcing simple, honest, and fast.
We built Medina Diamonds around one idea: the trade deserves a supplier that treats wholesale like a partnership, not a transaction. That means deep live inventory, transparent pricing, and a team that picks up the phone.
Every diamond we supply is independently certified — IGI or HRD Antwerp for lab-grown, GIA for natural. No exceptions. We work exclusively with registered businesses in the jewelry industry, so you can build confidently on top of what we deliver.
